    Summary
    This summary is machine-generated.

    Most humans cannot digest milk after weaning, a condition common in the U.S. A simple lactose tolerance test can diagnose this milk digestion issue.

    Area of Science:

    • Human physiology
    • Mammalian biology
    • Nutritional science

    Background:

    • Postweaning milk digestion inability is the norm for humans and land mammals, except in populations with long-standing dairying traditions.
    • Lactose intolerance affects a significant portion of the U.S. population, potentially around 30 million individuals, due to ethnic diversity.
    • Many individuals with lactose intolerance instinctively avoid milk to prevent symptom development.

    Purpose of the Study:

    • To highlight the prevalence of postweaning milk digestion inability in humans.
    • To emphasize the need for accessible diagnostic methods for lactose intolerance.
    • To describe a simple diagnostic test for lactose intolerance.

    Main Methods:

    • Review of accumulating evidence on milk digestion in humans and mammals.

  • Estimation of the prevalence of lactose intolerance in the U.S. population.
  • Description of a simple lactose tolerance test for diagnosis.

    • Main Results:

    • Evidence supports that inability to digest milk after weaning is the biological norm for most humans.
    • Approximately 30 million Americans may experience symptoms when consuming milk due to lactose intolerance.
    • A straightforward lactose tolerance test has been developed for diagnostic purposes.

    Conclusions:

    • Lactose intolerance is a widespread condition, reflecting a natural human physiological state.
    • The ethnic diversity of the U.S. contributes to the high prevalence of lactose intolerance.
    • A simple lactose tolerance test provides an accessible method for diagnosing milk digestion issues.
